This invention relates to the art oflocks and latches, and has particular reference to Y which will operate to hold the door open and;

- a fastener of the latch type for sliding doors.

Among the objects of my invention may be noted the following: to provide a doubleacting fastener or latch for sliding doors,

also hold the door closed; to provide a combination'of means, parts and devices specially'adapted to hold'the sliding door of an auto-truck cab in either an open or closed position; 'to'provide means for holding the sliding door-of an auto-truck cab in either an open or a closed position, coupled with means for readily shifting-the holding means from either the inside or outside of the cab,'so that, if the door be fastened open or fastened closed, the operator can readily manipulate the holding meansto release the cab may be prevented from sliding or shifttive means, for bringing about the foregoing 1 door; toprovide a combination-of means wherebyrthe sliding door; of an' auto-truck ing its position when open, and-also held' securely when closed regardless of the angle or inclination of the cab with reference to the traction surface of the truck; and to provide a combination of simple and eifecpurposes, whichare readily adapted toqthe sliding door and door-frame of an;- auto truckicab, and which are strong, durable I and/claimed.
